How Do Gas Lines Work

Distribution lines typically operate at less than one-fifth of their design pressure. As gas flows through the system, regulators control the flow from higher to lower pressures. If a regulator senses that the pressure has dropped below a set point it will open accordingly to allow more gas to flow.

How does gas move through pipeline?

Natural gas is moved through pipelines as a result of a series of compressors creating pressure differen- tials – the gas flows from an area of high pressure to an area of relatively lower pressure.

How deep are gas mains buried?

On average, main gas lines are usually found at least 24 inches deep, while service lines are usually 18 inches deep.
